How to remove the Qua RAT from PC?
Computer security is tested daily by hackers around the world. Companies spend millions on digital security, and consumers may be constantly exposed to malware threats that have evolved to insecure viruses such as the Qua RAT trojan.
Updates with patches are available all the time, but protections in operating systems are under attack. Viruses also penetrate the most advanced techniques. The Qua RAT quickly penetrates your PC system and destroys it.
What is Qua RAT?
The Qua RAT is a type of malware that misleads the user.
The Qua RAT masquerades as a legitimate program. The Trojan virus is harmless, but it is dangerous because it allows cybercriminals to get into the user's system. When a Trojan virus activates, it starts spying, collecting valuable data, and sending it to criminals.
In today's world, there are many more varieties of Trojans. Viruses know how to find the path to the user's computer to gain complete control over it. Also, Qua RAT collects information about the system to detect vulnerabilities. All collected information is further used to create ransomware, other viruses, and programs.
Detecting Trojan viruses, especially Qua RAT, is very difficult. It is essential to choose the right antivirus tool like AVarmor to protect your PC.

- The user opened the infected email, and the virus quickly got onto your PC.
- A pop-up ad attracted the user, and he clicked on it - the Qua RAT virus instantly got on your computer.

- Peer-to-peer networks are the primary carrier of Qua RAT viruses.
How Qua RAT works?
Qua RAT works the same way as other Trojans, pretending to be a legitimate program by hiding itself in the system and performing various malicious actions (theft of banking information, passwords, emails, etc.).
The Qua RAT Trojan copies its executable file to the Windows system folders once installed on the PC. The virus also modifies the registry.
Monitoring for the fake Qua RAT file?
Once you notice a Qua RAT file, there are two ways to check if it is legitimate or fake.

- Look at the Processes tab and look for Qua RAT.exe.
- Right-click on the file - Delete.
